2 Months No Refund

i purchased a dress from Spree and received the dress around the 20 January 2015. it cost R 275. The dress was to small and i advised Spree the very next day that i wish to return it. Approximately 3 days later, they sent someone to collect it and to date i have not been refunded, that is 2 months later. This is bad service and i understand the risk of purchasing clothing online but i will never purchase from Spree again if this is the level of the service or should i say ' non - service '. Very dissapointed
